I have a 48" orbit fixture on my 75G tank.... I have a question about the flourescents.
How often do you change the bulbs? I have heard that the bulbs lose luminoscity in the needed bandwidths after a length of time... just not sure what time that is, or even if it varies from bulb type to bulb type. I have 65W straight pin bulbs.
Any ideas?
